2.1.4 Power Supply / Fan Module (PSFM)
The RAID subsystem contains two 400W Power Supply / Fan Modules. All the
Power Supply / Fan Modules (PSFMs) are inserted into the rear of the chassis.
2.1.4.1 PSFM Panel
The panel of the Power Supply/Fan Module contains: the Power On/Off Switch, the
AC Inlet Plug, and a Power On/Fail Indicator showing the Power Status LED,
indicating ready or fail.
Each fan within a PSFM is powered independently of the power supply within the
same PSFM. So if the power supply of a PSFM fails, the fan associated with that
PSFM will continue to operate and cool the enclosure.
When the power cord connected from main power source is inserted to the AC
Power Inlet, the power status LED becomes RED. When the switch of the PSFM is
turned on, the LED will turn GREEN. When the Power On/Fail LED is GREEN, the
PSFM is functioning normally.
